We use Dameware for most of out in house support and occassionaly use radmin. Damewares has lots of potential customization plus can connect to users even if they don't have the client as it will prompt to install it for you and push it to them. Can connect by IP or comp name and has built in ftp file transfer options where u just drag a file from your pc to the program and it transfers to a hidden folder that you can access. http://www.dameware.com/ like i said i just use most of the defaults but seems like it has lots of customization
